AUTQMATIC wmnow CLOSER Filed Sept. 24, 1938 2 Sheets-Sheet 2 Inventor /07 "Fe Ze 7 PLzJQ/L Patented June 4, 1940 UNITED STATES PATENT OFFICE 1Claim.

The present invention relates to automatic window closing devices andhas for its primary object to provide a spring roller normally operatingto close the Window and providing a strip 5 of disruptable material forholding the roller against the tension of the spring to normally securethe same against operation, said material adapted to be ruptured by rainor consumed by fire to release the roller to operate in closing the 10window.

A further object is to provide an apparatus of this character of simpleand practical construction, which is eificient and reliable inperformance, relatively inexpensive to manufacture 15 and install inoperative position and otherwise well adapted for the purposes for whichthe same i i is intended.

Other objects and advantages reside in the details of construction andoperation as more 20 fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout and in which:

Figure 1 is a front elevational view of the 25 inside of a Windowshowing the same maintained in an open position.

Figure 2 is a fragmentary elevational view of the window taken from theoutside thereof;

Figure 3 is a vertical fragmentary sectional 30 view through the window,and

I Figure 4 is a detail of the spring roller with parts broken away andshown in section.

Referring now to the drawings in detail, where in for the purpose ofillustration I have disclosed 35 a preferred embodiment ofthe inventionthe numeral 5 designates a window frame Within which upper and lowersash 6 and 1, respectively,

are slidably mounted in the usual manner. To

the window sill 8 is secured a pair of spaced roller brackets 9 having aspring roller l rotatably supported thereon, one end of n the roller ibeing provided with a fixed trunnion ll rotatably supporting the rollerin one of the brackets while the other end of the roller is providedwith a recess l2 into which a shaft I3 is inserted and journaled in theend of the roller and forming a i rotatable support for said end of theroller.

A coil spring i4 is positioned on the shaft within the recess I2, oneend of the spring being secured 5 to the shaft, as at l5, while theother end of the spring is secured to the roller, as at Hi, the shaftbeing secured to the adjacent bracket against rotation whereby it willbe apparent that the rotation of the roller so as to place a ten- 55sion on the spring M will cause a windingof the roller when thesame isreleased.

A flexible member l6, preferably of wire, has its ends secured to theroller, as at H, and its intermediate portion inserted through a pair ofscrew eyes l8 secured in spaced relation to the lower edge of the lowersash 1 of the window. 5

To the inside of the sill 8 is secured a spring clampis adapted to clampone edge of a strip of paper 20 or similar disruptable material, thefree end of the paper being Wound one or more times around the roller IDwith portions of the 10 winding of the flexible member l6, as clearlyshown in Figure 4 of the drawings, the strip of paper holding the rolleragainst winding movement by the spring. One end of the paper strip isplaced in abutting engagement with the ends of the member I6 which areconnected with the roller and then the strip and portions of the memberl6 are Wrapped together around the roller until finally the parts of themember it pass out of the side portions of the winding of the paperstrip.

When securing the device in operative position, the window is raisedandtemporarily held by means of a hook 2| secured to one side oftheframe for engaging under the lower edge of the sash to hold the sameagainst downward movement while the paper 20 is being positioned on theroller lll. After the paper has been placed in position, the hook 2| isreleased and the window willbe held in a raised position, against theaction of the spring M by the paper 20. Should the, paper becomedisrupted or destroyed,

as by becoming subjected to rain or fire, the

roller ID will wind the flexible member l6" down-- wardly thus loweringthe sash,

It is believed the details of construction and manner of operation ofthe device willbe readily understood from the foregoing without furtherdetailed explanation.

Having thus described the invention, what I claim is: i A window closercomprising a spring roller, a

fixed mounting therefor, a flexible looped memher having intermediateportions attached to the window with its ends connected with the rollerand having portions adjacent said ends wrapped about the roller, whenthe window is in open position, a strip of material pervious to moisturehaving one end wrapped about the roller and engaged by parts of thewinding of the flexible member which holds said end of the strip to theroller and a clamp on the window frame for engaging the other end of thestrip."
